Important Note: At this stage it is highly
recommended to use the ORBISPHERE 323021
electrochemical cleaning and regeneration center
for improved sensor performance and a
noticeably extended sensor life. Detailed
information on how to use the cleaning and
regeneration center is included in the 32301
Operator Manual. The ORBISPHERE 32301 is a
very efficient cleaning and regeneration tool for
electrochemical sensors. This tool reverses the
electrochemical process that is taking place in the
sensor cell during normal operation. This
removes oxidation and at the same time
regenerates the surface of the electrodes. In
addition, the regeneration center offers a
continuity tester for checking the sensor
electronics.
Note: During this next step, it is very important to
ensure your finger does not come into contact with the
cathode (golden surface) as it could leave greasy
deposits on the surface.
